f COAL-CHUTE.

Application Vfiled March 26, 1914. Serial No. 827,451.

To all lwhom, t may concern: i

Be it known that I, ALBERT L. ADAMS, a citizen of the United States, residing at Cedar Rapids, in the county of Linn land State of Iowa, have invented a new and useful Coal-Chute, of which the following is a specication.

The present invention relates to improvements in coal chutes, the primary object of the invention, being the provision of a chute for attachment to or to be used in conjunction with a coal delivery wagon, the inlet end of the chute being provided with a removable reinforcing or auxiliary bottom to thus receive the greatest impact and wear due to the initial impact of the coal entering the chute, the extreme edge of the reinforcing or auxiliary bottom being provided with two sets of spaced fingers which act as guards to reduce the spilling of the coal due to an over-crowding at the mouth of the chute.

A further object of the present invention is the provision of a coal chute, in kwhich an auxiliary impact receiving bottom is insertible within the inlet end of the chute, and is provided with `means to coa'ct vwith the supporting lip of the chute at the end thereof to limit the distance of introduction of the auxiliary bottom into the chute and also to prevent the same from sliding further relatively to and upon the bottom of the chute.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. j l

In the drawings Figure'l is a perspective view taken from lthe inlet end of a coal chute, constructed according to and embodying the present invention. Fig. 2 is a longitudinal sectional view at the inlet end of the chute, clearly showing the Vmannerjof mounting the auxiliary vbottom therein. Fig. 8 is a section taken transversely of the chute upon the line 3 3 of Fig. '2.

Referring to the drawings, the numeral 1 designates the main body ofthe chute, Vwhich may be provided with parallel. or tapering guide walls 2, each ofV which is provided withl the inturned guiding and strengthen4 Specification of Letters Patent.

ing flange 3. These flanges and the angle at their junction with the walls, are protected and further strengthened by the angle irons 3', which are preferably riveted in position. The angle irons 3, adjacent the inlet end of the chute are each pierced by a rivet 4c, as is also the wall 2 and the upper end of the band 5, which is secured to and embraces the outer end of the chute, and carries the lip or flange 6, which provides a means to limit the outward movement of the chute relatively to the wagon.

In order to properly reinforce the bottom of the chute at its greatest wearing point, which is at the portion beyond the lip 6, is the plate 7, which is substantially the width of the bottom of the chute, between the walls 2, said plate 7 being slidable and insertible from and in the inlet end of the chute to be detachablyV held in place against upward displacement by the guiding cleats or fastenings 8, which are of such a size as not to interfere with the passage of the coal upon the plate 7 and between the walls 2.

To yprovide a means to prevent the coal from over-crowding and spilling from the inlet end of the chute and also to limit the introduction of the auxiliary bottom 7 within the chute and preventing it from sliding farthertherein, the flat fingers or prongs 9 and 10, are formed at one end ofthe plate 7, by producing parallel slits in the end thereof, and alternatingly bending the fingers 9 and l0 in opposite directions and at right angles to the plane of the plate 7, the {ingers when the plate 7 is in proper assembled position, being in a plane slightly. beyond the outer face of the lip 6, as clearly shown in Figs. 1 and 2.

By this construction of coal chute, it is evident that the'plate 7 will form a reinforcement for the bottom of the chute at the inlet end thereof, and that by reason of the fact that the same is removably secured in place, the same may be removed by being slidably withdrawn through the inlet end of the chute and reversed when it itself is too greatly worn, the fingers 9 and 10, thus being properly positioned as theyare so disposed asto project beyond either side of the plate 7. It will thus b e seen that when the auxiliary bottom 7 is in position, the de-l pending fingersQ will abut the outer face of thel lip 6 and thus limit the inward movement of the auxiliary bottom relatively to the inlet end of the chute, while the up- Wardly projecting fingers 10 will provide a barrier across the inlet end of 4the chute ,to Y prevent the back crowding of the coal which is delivered upon the auxiliary bottom 7.

What is claimed is:

l. A coal chute, a reversible slidably mounted auxiliary reinforcing bottom insertible through the inlet end of the chute for disposition above and in contact with the main bottom of the chute to receive the initial impact of the coal dumped into the chute, and means attached to the side of the chute for engaging the upper surface at its edge of the auxiliaryl bottom for holding the same relatively upon the main bottom of the chute. j

2. A coal chute, a reversible and detachable auxiliary and reinforcing bottom mounted at the inlet end and oppositely eX- tended and spaced fingers. carried by the reinforcing bottom and for projection across the extreme inlet end of the chute to formV a barrier to prevent the spilling of material ydue to the back crowding inthe chute.

k3. A coal chute having a main bottom, a slidably mounted removable plate insertible at the inlet end of the chute to be placed coextensive with the main bottom, said plate constituting an auxiliary covering bottom for the main bottom of the chute, and guiding means attached to the sides of the chute and projecting in contact withV the top surface of the edge of the removable plate for holding the plate upon the main bottom.

4. A coal chute having the main bottom thereof at the inlet end reinforcedby a slidably mounted reversible plateinsertible at the inlet end of the chute to be placed c0- extensive with the main` bottom said-plate constituting an auxiliary covering` bottom for the main bottom of the chute, guiding means for holding the plate upon the main bottom, and means for limiting the inward movement of the plate.

5. A .coal chute, a detachable plate constituting auxiliary reinforcing bottom for the inlet end of the chute, saidplate Y being provided with bent up spaced fingers to forma barrier across the extreme inlet end of the chute.

6. A coal chute, a detachable and re yversible plate constituting an auxiliary reinforcing bottom for the inlet end of the chute, said plate being provided with two sets ofspaced fingers formed at one end y one set upon each side of the plate, said fingers forming barriers across and at the extreme inlet end of the chute. v

7 A coal chute, having a bottom and up- Gopies of this patent may be obtained ,fon ihrev cents each, by addressing: the Commissioner ,o f Patenti, n

standing guiding walls, a retaining lip carried-by the .bottom and walls at the inlet end of the chute, a plate slidably mounted above and in contact with the bottom and insertible in the inlet end of the chute, said plate constituting an auxiliary bottom. at such point,` and means carried by the plate and Vcooperating with the lip to limit the distance of insertion of the plate within. the chute. f 8. A coal chute,having a bottom and upstanding guiding Walls, a retaining lip carried by the bottom and walls at the inlet end of the' chute, a reversible plate slidable' through the inlet end of the .chuteabove and in contact with the bottom, said plate constituting an auxiliary bottom Vfor the chute, a barrier at the free end of the plate extending across V:the extreme inlet Vend of the chute, and guiding and fastening means to hold the plate upon the bottom of the chute. Y i t j 9. A coal chute, having a bottom and upstanding guiding Walls, a plate'slidable in the inlet end of the chute for dispositionabove and in contact with the bottom, said plate constituting an auxiliary bottom for the chute at such point, and oppositely exi tending spaced ingers carried by one end of the plate for projection above and below the bottom of the chute, the ingersbeglow constituting a means for limiting the insertion of the. plate withinV the inlet end ot the chute while the lingers abogve constitute a barrier to prevent the back crowding of material out of the chute.

10. A coal chute, having a bottom andY stitutea barrier to prevent .the back ,crowd 'l ing of material out of the chute, and means carried by the chute lfor guiding the plate and" for-holding.: thesame Vrelatively to and above the bottom of the'jchute.` Y
